Scale is the problem. Just constraining yourself to the US and using the arbitrary 2000 calories per day per person, the US needs to produce about 2.4 x 10^14 food calories per year. I'll leave it as an exercise to the reader to figure out how many greenhouses that is or how many 3d hydroponic farms, but the counter offer is a few thousand square miles of corn. |
